This article will introduce common failure diagnosis and troubleshooting of motorized pulley to you continuously.
5.Oil leakage of junction box (internal driver).
Troubleshooting method: Check whether the oil level is too high or not. Remove the junction box and tighten the grease seal plug.
6. Big pulley noise.
Troubleshooting method: If noise of newly installed pulley is big, please increase the support rigidity and check the pulley, shaft coupling, motor installation coaxality simultaneously. The method is to remove the pulley from the stand, test run the pulley separately. If the noise becomes smaller, it indicates that the support rigidity needs to be increased.
7.Pulley doesn’t rotate after the backstop pulley is connected to the power supply.
Troubleshooting method: Power supply sequences have errors, the power supply should be disconnected immediately and change the sequences of power supply in order to get the correct sequences of connection.
8. Pulley is reversed when the backstop pulley is disconnected to the power supply.
Troubleshooting method: Check if backstop device is fault or wear and tear.
